A pair of side grooves is formed in the side wall of the bone nail body. The two side grooves are communicated with the expansion hole. Each thread strip is arranged inside each side groove. The inner side wall and the outer side wall of each thread strip are respectively in an arc plane with threads. The directions of the threads of the outer walls of the two thread strips are opposite. The thread strips are in clearance fit with the side grooves where the thread strips are arranged, and can horizontally move inside the side grooves where the thread strips are arranged along the side direction. According to the thread discontinuous detachable expansion bone nail, possibility that the bone nail drops out along the clockwise direction or along the anti-clockwise direction, an fixing effect is improved, and meanwhile operation is simpler and more convenient to achieve, operation damage is smaller, and safety is higher.
